New research helps explain how progesterone preventspreterm birth

SAN FRANCISCO, FEB. 10, 2011 -- Research presented today at the 31st Annual meeting of the Society for Maternal-Fetal Medicine (SMFM) -- The Pregnancy Meeting™ has found that three proteins known as XIAP, BID, and Bcl-2 are responsible in part for the success of progesterone treatments in the prevention of preterm labor. They may also play an important role in triggering normal labor.

Long- and short-sleeved physician workwear receive same amount of bacterial and MRSA contamination

Governmental agencies in the United Kingdom recently instituted guidelines banning physicians' white coats and the wearing of long-sleeved garments to decrease the transmission of bacteria within hospitals due to the belief that cuffs of long-sleeved shirts carry more bacteria. However, a new study published today in the Journal of Hospital Medicine shows that after an eight-hour day, there is no difference in contamination of long- and short-sleeved shirts, or on the skin at the wearers' wrists.

Cancer breakthrough to prevent heart failure and increase survival rates

A breakthrough by scientists at Queen's University Belfast could help reduce heart failure in cancer patients around the world, and ultimately increase survival rates.

Scientists at Queen's Centre for Vision and Vascular Science have discovered the role of an enzyme which, when a patient receives chemotherapy, can cause life-threatening damage to the heart. This has, until now, restricted the amount of chemotherapy doses a patient can receive; but while protecting the heart, this dilutes the chemotherapy's effectiveness in destroying cancerous tumours.

Time to reopen PFI contracts

It is time to reopen private finance initiative (PFI) contracts say leading public health physician, Professor Allyson Pollock, and colleagues on bmj.com today.

Professor Pollock, who is based at the Centre for International Public Health Policy at the University of Edinburgh, argues that "NHS PFI contracts are not good value and are endangering patient care".

Stroke in Mexican-Americans expected to rise 350 percent in next 40 years

Strokes will increase dramatically over the coming decades, with increases being considerably steeper in Mexican-Americans compared with non-Hispanic whites, according to research presented at the American Stroke Association's International Stroke Conference 2011.

"The tremendous number of strokes projected has large personal, social and economic consequences for the United States," said Shawnita Sealy-Jefferson, M.P.H., an investigator at the School of Public Health at the University of Michigan in Ann Arbor.

Everolimus improves progression-free survival for patients with rare pancreatic cancer

Houston - In an international Phase III randomized study, everolimus, an inhibitor of the mammalian target of rapamycin (mTOR), has shown to dramatically improve progression-free survival for patients with advanced pancreatic neuroendocrine tumors (pNET), according to researchers from The University of Texas MD Anderson Cancer Center.

Rice University technology in human trials to spot cardiac disease, cancer, drug abuse

Heart disease is a silent killer, but new microchip technology from Rice University is expected to advance the art of diagnosis.

During National Heart Health Month, Rice Professor John McDevitt will discuss the potential of this technology to detect cardiac disease early at the annual meeting of the American Association for the Advancement of Science (AAAS) in Washington, D.C., Feb. 17-21. Cardiac disease is the focus of one of six ongoing major clinical trials of Rice's programmable bio-nano-chips (PBNCs).

Key role proposed for pediatricians in curbing tobacco use

New Rochelle, NY, February 9, 2011—Nicotine addiction usually begins during the critical teenage years, and pediatric healthcare professionals can play a prominent role in promoting a tobacco-free lifestyle among children and adolescents, as described in an article published online ahead of print in Pediatric Allergy, Immunology, & Pulmonology, a peer-reviewed journal published by Mary Ann Liebert, Inc. The article is available free online.

Nanonets give rust a boost as agent in water splitting's hydrogen harvest

CHESTNUT HILL, MA (2/9/2011) – Coating a lattice of tiny wires called Nanonets with iron oxide – known more commonly as rust – creates an economical and efficient platform for the process of water splitting, an emerging clean fuel science that harvests hydrogen from water, Boston College researchers report in the online edition of the Journal of the American Chemical Society.

Omega 3's -- more evidence for their benefit

Omega-3 fatty acids –fats commonly found in fish oil – were shown several years ago to prevent retinopathy, a major form of blindness, in a mouse model of the disease. A follow-up study, from the same research team at Children's Hospital Boston, now reveals exactly how omega-3's provide protection, and provides reassurance that widely used COX-inhibiting drugs like aspirin and NSAIDs don't negate their benefit. The findings, published in the February 9th issue of Science Translational Medicine, also suggest that omega-3's may be beneficial in diabetes.

Photodynamic therapy against cancer

Tumor cells have several routes that enable them to move from the primary tumor to distant tissues, a process called metastasis. It is metastasis of the primary tumor that kills most cancer patients. One of the least studied routes of metastasis is the lymphatic system. Many tumors produce factors that promote the formation of new lymphatic vessels (lymphangiogenesis). The newly formed lymphatic vessels enable tumor cells to travel from the primary tumor to the regional lymph nodes from whence they can spread throughout the body.

Saint Louis University findings: Don't pitch stockpiled avian flu vaccine

ST. LOUIS -- A stockpiled vaccine designed to fight a strain of avian flu that circulated in 2004 can be combined with a vaccine that matches the current strain of bird flu to protect against a potential pandemic, researchers from Saint Louis University's Center for Vaccine Development have found.

Researchers: Elderly patients 4 times more likely to die from treatment complications

Research by the American Academy of Family Physicians demonstrates that vulvar cancer occurs most frequently in women age 65 to 75 years of age. Thirty percent of patients with vulvar cancer are age 70 or older, and the rate increases with age, reaching a peak of 20 per 100,000 women by 75 years of age.

Searching for the soul of the genome

The discovery that a "gene desert" on chromosome 9 was a hotspot for coronary artery disease (CAD) risk was among the highlights of findings produced recently by genome-wide association studies, which compare the genomes of many people for genetic variations and have been broadly used in the past few years to study hundreds of diseases and complex traits. Gene deserts are large genomic segments devoid of genes.

Skin cells help to develop possible heart defect treatment in first-of-its-kind Stanford study

STANFORD, Calif. — Using skin cells from young patients who have a severe genetic heart defect, Stanford University School of Medicine scientists have generated beating heart cells that carry the same genetic mutation. The newly created human heart cells — cardiomyocytes — allowed the researchers for the first time to examine and characterize the disorder at the cellular level.
